larvae of the first-named species feed upon ehn, sallow, birch, 

 wliitethorn, strawberry, &c. : very few larva? of C. immanata 

 have been found, and I believe they have all occurred upon 

 the wild strawberry ; they may, however, also feed upon 

 alder, but this tree does not exist in our forest, where C. 

 immanata was formerly very common. I have fed all the 

 larvae, which 1 have reared from the eggs, upon strawberry. 

 The late Mr. Hopley kindly procured me some eggs from 

 Orkney in August last year. These hatched early in April, 

 and the moths appeared the beginning of July : they are the 

 most remarkable specimens that I have seen, and are quite 

 different in colour from any that I have bred before, some of 

 them being black with clearly-defined white markings. —

Yellow Females of Colias Hyale. — Since reading the 

 remark by Mr. Doubleday respecting the yellow female of 

 Colias Hyale taken in Vienna, I have looked over my series 

 of this insect, and find four specimens which are of the 

 yellow colour of the males, but which from the stoutness of 

 the abdomen I should decidedly consider to be females. 

 One of these (captured by Mrs. Cox) has a beautiful tinge of 

 the colour of Edusa in the middle of ihe fore wings, as 

 mentioned by us at p. 179 of No. GO of the 'Entomologist' 

 (December, 1868). As I have given and exchanged many 

 specimens without closely examining them, it is very likely 

 there were many other yellow females among our eight hun- 

 dred specimens, captured by us near Margate in July and 

 August, 1868. I should be very glad to show these varieties 

 to anyone caring to look at them. — H. Rutnsay Cox ; West

[I have carefully examined these specimens in company 

 wilh Mr. Bond, and we are both decidedly of opinion that 

 they are females : it must therefore be concluded that we 

 have two forms of female in Hyale corresponding with those 

 of Edusa, but that the numerical ratio of the pale one is very 

 much greater in Hyale than in Edusa, — E. Newman.'\

 me in opinion that the species there described is not the
